 Doctors who specialize in the alignment of the atlantooccipital axle junction, it's just a term to say between your skull and your first bone, your first bone, your second bone, doctors who work on the alignment of that will often find people see their blood pressure drop drastically. In fact, a couple of weeks ago, I had a patient who physically came in, had one of the watches on and said, look, look, 140 over 90.
